Playing a Disc
To play a disc, gently insert the disc with the label side
up into the loading slot. The DVD player will continue
loading the disc and the player will automatically start,
if the vehicle is in RUN, ACCESSORY, or when
RAP is active.
If a disc is already in the player, press the play/pause
button on the DVD player faceplate or on the remote
control.
Some DVDs will not allow fast forwarding or skipping of
the copyright information or the previews. Some DVDs
will begin playing after the previews have nished. If the
DVD does not begin to play the main title, refer to the
on-screen instructions.
Stopping and Resuming Playback
To stop playing a disc, press and release the stop button
on the DVD player faceplate or the remote control.
To resume playback, press the play/pause button on
the DVD player faceplate or the remote control.
The movie should resume play from where it was last
stopped, if the disc has not been ejected and the
stop button has not been pressed twice. If the disc has
been ejected or if the stop button has been pressed
twice, the disc will resume play at the beginning.
Ejecting a Disc
Press the eject button on the DVD player faceplate to
eject the disc. There is not an eject button on the
remote control.
If a disc is ejected from the player, but is not removed,
the DVD player will reload the disc after a short period
of time. The disc will be stored in the DVD player.
The DVD player will not resume play of the disc
automatically.
Remote Control
To use the remote control, aim it at the transmitter
window below the video screen and press the desired
button. Direct sunlight or very bright light may affect the
ability of the RSE system to receive signals from the
remote control. If the remote control does not seem to
be working, the batteries may need to be replaced.
See “Battery Replacement” later in this section.
Objects blocking the line of sight may also affect the
function of the remote control.
Notice:Storing the remote control in a hot area or
in direct sunlight may damage it, and the repairs
will not be covered by your warranty. Keep the
remote control stored in a cool, dry place.
To extend the life of the batteries, the remote control
does not have a press and hold feature.

compartment.
3. Close the battery door securely.
If the remote control is to be stored for a long period of
time, remove the batteries and keep them in a cool,
dry place.

{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see
it or smell it, so you might not know it is in
your vehicle. Clear away snow from around
the base of your vehicle, especially any that
is blocking your exhaust pipe. And check
around again from time to time to be sure
snow does not collect there.
Open a window just a little on the side of
the vehicle that is away from the wind.
This will help keep CO out.Run your engine only as long as you must. This
saves fuel. When you run the engine, make it go a
little faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get
and it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.
Then, shut the engine off and close the window
almost all the way to preserve the heat. Start the
engine again and repeat this only when you feel
really uncomfortable from the cold. But do it as little
as possible. Preserve the fuel as long as you can.
To help keep warm, you can get out of the vehicle
and do some fairly vigorous exercises every half hour
or so until help comes.

Engine Oil
If the CHECK OIL LEVEL message appears on the
instrument cluster, it means you need to check
your engine oil level right away.
For more information, see CHECK OIL LEVEL under
DIC Warnings and Messages on page 3-56.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 5-12
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.
5-15

For example, if someone puts in brake linings that
are wrong for your vehicle, the balance between your
front and rear brakes can change — for the worse.
The braking performance you have come to expect can
change in many other ways if someone puts in the
wrong replacement brake parts.
Battery
Your vehicle has a maintenance free battery. When
it is time for a new battery, get one that has the
replacement number shown on the original battery’s
label. We recommend an ACDelco
®replacement
battery. SeeEngine Compartment Overview on
page 5-12for battery location.
Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm.
Wash hands after handling.
Vehicle Storage
If you are not going to drive your vehicle for 25 days
or more, remove the black, negative (−) cable from
the battery. This will help keep your battery from
running down.
{CAUTION:
Batteries have acid that can burn you and
gas that can explode. You can be badly hurt
if you are not careful. SeeJump Starting on
page 5-42for tips on working around a battery
without getting hurt.
